基于AVL数据的公交运行可靠性评价及影响因素分析
AVL-based evaluation and influence factors analysis of bus service reliability
摘要
Abstract
This paper made a quantitative analysis of bus service reliability by the automatic vehicle location record of route 48 throughout a day in Chengdu.It firstly validated a clear monotonic positive association between the mean value and logarithm standard deviation of bus travel time.Then it quantized indexes including section's length,the number of signal intersection and station,bus lane's length,periods of time as well as land-use intensity so that it could established a multiple-linear regression model to explore factors which could be having an influence on the volatility of travel time.Considering the features that the volatility was back stations propagation with bus running,this paper added an index to describe the volatility in pre stations.The result shows that there is high correlation of bus service reliability between adjacent stations.关键词
